Description of problem:
When virt-who run at non-background mode, on the terminal side, it will show "/usr/share/virt-who/virt/hyperv/ntlm.py:24: DeprecationWarning: the md5 module is deprecated; use hashlib instead from md5 import md5"

Version-Release number of selected component (if applicable):
subscription-manager-1.12.10-1.el6.x86_64
python-rhsm-1.12.5-1.el6.x86_64
virt-who-0.10-4.el6.noarch
katello-headpin-1.4.3.26-1.el6sam_splice.noarch
candlepin-0.9.6.4-1.el6sam.noarch

How reproducible:
Always

Steps to Reproduce:
1. Register system to SAM server
2. Configure virt-who in libvirtd mode as the following:
[root@hp-z220-03 ~]# cat /etc/sysconfig/virt-who 
    VIRTWHO_BACKGROUND=0
    VIRTWHO_DEBUG=1
    VIRTWHO_INTERVAL=5
3. Start virt-who service , check the output message on the terminal
# service virt-who restart

Actual results:
On the terminal, It will show DeprecationWarning as the following:
Stopping virt-who:                                         [FAILED]
Starting virt-who: INFO: No configurations found, using libvirt as backend
DEBUG: Starting infinite loop with 2 seconds interval
/usr/share/virt-who/virt/hyperv/ntlm.py:24: DeprecationWarning: the md5 module is deprecated; use hashlib instead
  from md5 import md5
Creating new instance of LibvirtMonitor
DEBUG: Starting libvirt monitoring event loop

Expected results:
I suggest it needn't to show the message of "/usr/share/virt-who/virt/hyperv/ntlm.py:24: DeprecationWarning: the md5 module is deprecated; use hashlib instead from md5 import md5" on the terminal side.

Additional info:
When virt-who run at background mode, it hasn't this problem.
